trezor or case have other attack vectors
Oh, what are their weaknesses? I was not aware that a trezor had any ?
I believe people were able to extract private keys by measuring electric noise or something, that's being created by the processor while processing the keys. It really is quite a remarkable method, I don't know how easy it is to apply it, though!
Seems like it has been fixed by satoshilabs but the fact that it was possible means that there may be other vulnerabilities.
I guess over time hardware wallet companies will improve.
